So do the people who made the art used to train these things.
I dropped out of fucking high school and was homeless couch surfing in LA for years trying to break into steady VFX work, I don't think for a lack of skill/blood/sweat/tears[1]. I'm well aware artists need to eat.
The problem isn't technological progress, (jfc this is all open source!!! stability is doing god's work by undermining the value of ghouls who try to restrict access to these models for personal profit). It's certainly not that copyright is too weak in preventing people form building off the aggregate styles and work of artists. I learned style by fucking copying the masters[2]!! This is how art is supposed to work. The problem it's the disgusting economic/political system that has twisted copyrights and patents into a device to enable rent seeking for those who can afford to purchase/commission them rather than protecting the innovation and creativity that they were meant to.

So many artists copy/adapt Disney's style totally anonymously for example. Should they be paying royalties to Disney?
As a human being, if I browse DA and reference other people's work/styles while I muck about on a graphics tablet am I in the wrong?
It's only relevant when taking a very logical/semantic view of the situation, when you take a more holistic view it breaks down. The scale and implications of the two things you're comparing are completely different. While I probably agree with you in general I think these sorts of arguments don't really help people understand our point of view because they sidestep the economic and social implications which are at the heart of this.
